Incumbent Andrés Fontecilla of Québec solidaire leads trader pricing in the Laurier-Dorion riding ahead of the October 5 Quebec general election. Fontecilla has represented the Montreal-area seat since 2018, drawing on established local support in a diverse district with strong prior QS performance. Recent polling aggregates position the race as competitive between Fontecilla and Liberal challenger Randy Legault-Rankin, with Parti Québécois candidate Kelly Lazo de la Vega and smaller-party options trailing further behind. The nomination period closed in mid-September without major disruptions, leaving the contest centered on party momentum and riding-specific factors that sustain Fontecilla's advantage in market-implied probabilities.
